function Clear-DriveSpace {

    <#
.SYNOPSIS
Clear-DriveSpace takes a computer name and runs through a set of processes that clears out unused drive space on a local computer.

.DESCRIPTION
Clear-DriveSpace is a tool that can be run on systems with low drive space. It uses TreeSize after the program is finished executing to display the remaining drive space and what is using up most of it. The tool can only be run on systems where a GUI is installed, due to TreeSize requiring a GUI to view what is utilizing drive space, allowing the user to manually remove remaining files.

.PARAMETER ComputerName
ComputerName is a required parameter for this script. You can type localhost to run it on the current system or the current hostname.

.EXAMPLE
Clear-DriveSpace -ComputerName "Shanelaptop"

.NOTES 
Must be run as an administrator.
Must be running at least PowerShell Version 5.0 - check with $PSVersionTable.
